GetListingsPage


              func GetListingsPage(offset, limit int) string

GetListingsPage returns a page of active listings, one per line:

Example

1collectionID|tokenID|seller|price|createdBlk

Addresses are FULL (never truncated). offset/limit window the insertion-ordered listing set; limit is clamped to [1, MaxPageSize].

Command

gnokey query vm/qeval -remote "https://rpc.test13.testnets.gno.land" -data "gno.land/r/samcrew/memba_nft_market_v3_1.GetListingsPage(,)"

Result

GetOffersForToken


              func GetOffersForToken(collectionID, tokenID string) string

GetOffersForToken returns the active offers on one (collection, token), one per line:

Example

1buyer|amount|createdBlk

It uses a PREFIX-RANGE scan over the offer tree — offerKey is "collection:token:buyer", so the range ["collection:token:", "collection:token;") reads only this token's offers, never a full-tree scan. This is the read that finally lets the frontend wire accept-offer and show a token's offers (no offers getter existed before v3.1).

Command

gnokey query vm/qeval -remote "https://rpc.test13.testnets.gno.land" -data "gno.land/r/samcrew/memba_nft_market_v3_1.GetOffersForToken(,)"

Result

ListNFT


              func ListNFT(cur realm, collectionID string, tid grc721.TokenID, price int64)

ListNFT lists an NFT for fixed-price sale. PREREQUISITE: Owner must call memba_collections.SetApprovalForAll(collectionID, marketplace, true) first so MarketTransfer can execute on behalf of the seller.

MarketAddress


              func MarketAddress() string

MarketAddress returns this engine realm's own address — the operator a seller approves on the collection (SetApprovalForAll) and the address the collection registers via RegisterMarket. Exposed so the frontend and the deploy ceremony can read the deterministic address directly instead of hardcoding it.

Command
